| 103 `cascade-transition` slides the children of a container up in sequence, creating
a |
| 104 reverse waterfall effect. It works well with both grids and lists. Configure the |
| 105 duration of the transition with the global variable `CoreStyle.g.transitions.cas
cadeDuration`. |
| 106 |
| 107 Example: |
| 108 |
| 109 <core-animated-pages transition="cascade-transition"> |
| 110 <section> |
| 111 <div id="container" cascade> |
| 112 <div>item 1</div> |
| 113 <div>item 2</div> |
| 114 <div>item 3</div> |
| 115 <div>item 4</div> |
| 116 <div>item 5</div> |
| 117 <div>item 6</div> |
| 118 <div>item 7</div> |
| 119 </div> |
| 120 </section> |
| 121 <section></section> |
| 122 </core-animated-pages> |
| 123 |
| 124 In the above example, the immediate children of `#container` will slide up in |
| 125 sequence when the page transitions from 0 to 1. |
| 126 |
| 127 The items can optionally fade in as they slide. Add the `fade` attribute to |
| 128 the container to do that and configure the duration of the opacity transition wi
th |
| 129 the global variable `CoreStyle.g.transitions.cascadeFadeDuration`. |
